CAR-VENTI LATO R.

SPECIFICATION forming part of Letters Patent No. 415,360, dated November 19, 1889.

Application filed July 24, 1889.

To @ZZ whom ib may concern.-

Be it known that l, JOHN V. FOWLER, a citizen of the United States, and a resident of Brooklyn, in the State of New York,have invented a new and useful Improvement in Car-Ventilators, of which the following is a specification.

This invention relates to means for pivoting, operating, and fastening the side windows or ventilator-sashes in the domes of street-cars and other railwaycars having Bombay and monitor roofs.

The invention consists in certain novel combinations of parts, hereinafter set forth and claimed.

The objects of the invention are, first, to so pivot such ventilator-sashes that two or more on one side may be securely coupled together, so as to be operated and fastened by one and the same device without obstructing the glass and without subjecting it to torsional strain, so that oblon g sashes of any required length may be so coupled together end to end; secondly, to provide for readily operating such sashes, and at the saine time for securely fastening them in any of their positions by a simple screw-and-sectordevice, and, thirdly, to combine the pivoting, operating, and fastening devices above named in a compact and sightly arrangement of parts.

Three sheets of drawings accompany this specification as part thereof.

Figure 1 of the drawings, Sheet 1, represents a face view from inside a car of a pair of partly-opened ventilator-sashes, their frames and adjoining parts provided with my devices. Fig. 2 represents an outside view of the same car portion, showing the ventilator-sashes closed and Fig. 3 represents a vertical section on the line 3 3, Fig. 2, enlarged one diameter. Fig. l, Sheet 2, represents a like section on the line 1 l, Fig. 2. Figs. 5 and 6 represent longitudinal sections through the pivot-bearings on the line 5 6, Fig. el; and Figs. 7 and 8 represent large scale views of the respective pivot-bearings detached in the two positions of each. Fig. 9, Sheet 3, represents a face view from inside a car of a modified arrangement of my ventilator-operating devices. Fig 10 represents a plan view of the same sectionized in a Serial No. 318,477. (No model.)

broken plane, which is indicated at 10 in Fig. 9. Fig. 11 represents a vertical section on the line 11 11, Fig. 9, enlarged one diameter, showing details with the aid of dotted lines;

and Fig. l2 represents a like vertical section dome are provided with horizontal pivot-bearings A, B, or A', and two or more endwiseadjoining ventilator-sashes V are provided correspondingly with pivot attachments C C C2 or C3 C4 C5, which rigidly connect the sashes by horizontal pivots p and brace the same against torsional strain by attaching-plates extended across the corn er-joints of the sashes, as shown in Figs. 2 and 9. All the sashes 011 one side of a dome may thus be coupled to gether, as indicated in Figs. 9 and 10; or they may be coupled together in separately-adjustable pairs, as indicated in Figs. 1 and 2. A toothed sector D or D is rigidly connected with one of the pivots, and preferably with the central pivot of the pair or series of ventilator-sashes V, and is meshed by an endless screw or worm E, which is carried by a short vertical shaft F within the dome. The shaft F is held in place and supported against displacement downward by a bearing-bracket G, attached to the inner face of the longitudinal sill S of the dome, its bearing orbearings embracing the shaft below a shoulder on the latter. The shaft is supported at its upper end by an inverted step-bearing formed in or attached to a rib R of the dome roof. A hand-wheel H, made fast on the lower end of the shaft F, provides for readily turning the shaft by hand, and thereby turning the worm E and working the sector D, so as to simultaneously operate the pair or series of ventilator-sashes V, as may be desired. At rest the worm E, supported endwise by the shaft F and its bearings and coacting through the sector D with the connected sashes,automati cally and securely fastens the latter open, as

shown in Fig. l and in dotted lines in Figs. 4 and 12; closed, Aas shown in Figs. 2, 3, 9, and 11, and in full lines in Figs. 4 and 12, or in any other position in which they may be left when the hand is removed from the handwheel H.

In the arrangement illustrated by Figs. l to 8, inclusive, Sheets l and 2, the stiles S S2 are provided outside with peculiar pivot-bearings A B, Fig. 2, &c. (Shown detached by Figs. v7 and 8.) Two patterns of these suffice,

each being invertible for different positions, as illustrated in the igures.

their peculiar pivot attachments C C C2. The pivot-'bearings A and the pivot attachments C C coactat the adjoining ends of the sashes, i and said pivot attachment C carries the pivot p, Figs. '3 to 5, common to both attachments,

the attachment C having a socket, within which its end of the pivot is secured against turning by a `through -screw t, Fig. 5. The pivot-bearings B and the pivot attachments C2 coact at the outer ends of thepair orseries ofsashes, and one lpattern of each suffices, as'

illustrated by Figs. -2 and 8. Between'its pair of pivot-bearings A Vthe pivot @,or'one such pivot, as the case may be, of each pair or series of ventilator-sashes, is .provided with a toothed sector D, made fast uponthc vpivot in proper position -by a screw s, and extending.

`ix'i'ward through la recess in the sti-le S to the worlm jE,as shown in Figs. l, 2, and 4.

In ythe arrangement illustrated by Figs. 9 yto 12'on Sheet 3 of the drawings all the attachments are brought within the dome, so

to assist in decorating the interior, and so as In this to vbe .protected against the weather. arrangement vsuitable pivot bearings A', which may be of one pattern, are affixed to the stiles S2 inside, and pivot attachments C3 Ct-C5 are affixed to the inner surfaces of the ventilator-sashes V, the attachments C3 and C4, having the pivots p integral therewith, and theattachments-C, having sockets fitted to squares, for example, on the extremities of The ventilatorsashes V are also provided externally with My devicesare shown applied to the ventilator-sashes of monitor car-roofs. Their application to those of Bombay roofs and other like modifications will be readily effected by car-builders without further description.

Having thus described the said improvement, I claim as my invention and desire to patent under this specificationl. In combination with two or more oblong ventilator-sashes adjoining each other end to end and with the car-dome stiles between which they are fitted, pivot-bearings attached to said stiles, and pivot attachments affixed to the respective sashes and having attaching-plates .extended across the corner-joints of each sash, one of saidpivot attachments carrying the pivot commonA to two at each `point where two of the 'sashes adjoin,and another of them having a socket which receives said pivot and provided with means whereby it is made 'to turn with the `pivot, and thus to turn the sash to which it is affixed, substantially as `hereinbei-o'respecified.

2. In combination with a car-'dome frame and its movable ventilator-sashes, a horizontal 4pivot fcornmon to two endwise-'adjoining sashes and rigidly 4connected with both, a toothed sector rigidly "connected with said pivot-,a worm meshing said sector, a vert-ical shaft which carries said worm, bearings for said shaft which limit it to rotation, `and meansifor turning it by hand, substantially as hereinbefore specified.

The combination, in acar-dome of side 5a toothed 'sector rigidly connected 'with one of the pivots, a worm within the'dome-meshing said sector, a short vertical "shaft which carries said worm,-bearings 4for -said `shaft which limit it to rotationfand a-"hand-:wheel fast on its lowerfend, 'substantially'as 'hereinbefore specified.
